Theodori Prisciani Euporiston libri III, cum physicorum fragmento et additamentis pseudo-Theodoreis, editi a Valentino Rose ; accedunt Vindiciani Afri quae feruntur reliquiae Lipsiae 1894 (Bibliotheca Scriptorum Graecorum et Romanorum Teubneriana).
Of Theodorus Priscianus a treatise on pathology has come down to us, in its entirety, bearing the title Euporiston. This, at an early stage, was written by Theodorus in Greek, a work that has not come down to us, and later the author himself translated it, probably by reducing it, into Latin, thus entering the bilingual environment of late antique Africa in which personalities such as Caelius Aurelianus and Cassius Felix worked. It is a compendium of therapeutics consisting of three books, each with its own title: Faenomenon, Logicus and Gynaecia. The first book deals with the infirmities that affect the body externally, described a capite ad calcem, according to the usual criterion for this type of treatise; the second deals with internal pathologies divided into acutae and chronicae, while the third, dedicated to an obstetrician named Vittoria, deals with gynaecological diseases. This last book also had an independent transmission from the rest of the work.
The text, with an eminently practical slant, is intended to be a collection of hand remedies to help the sick quickly. Theodorus Priscianus is an eclectic, but he is close to the methodical school, especially when speaking of ailments that affect the body internally, yet he leaves out theoretical disputes. For him, the optimal outcomes of practical medicine based on simple recipes and easily procured remedies are more important. In doing so, Theodorus is an interpreter of the trend in medicine of his time, namely to reduce majestic therapeutic works into writings for everyday practice. The considerable interpolations introduced into the original text (the so-called Pseudo-Theodorus) show that the treatise did indeed spread and was used by late antique and medieval physicians.
